Letters Pam No. 103, 22, dated May 31, 1870.

The Schedule referred to in these Letters Patent and making part of thesame.

I, IsAAo B. KINKEAD, of Watrtown, in the county of Washington and Stateof Ohio, have invented an Improved Drying-House or Kiln, for desiccatiugfruits, vegetables, 85c, of which the following is a specification.

My invention relates to an improvement in the construction of dry-housesor kilns for. drying fruits,

' &c., by constructing the same of two or more superimposed compartmentsor chambers, each made distinct, accessible respectively from oppositeends of the structure, and separated by a continuous flue extending fromthe furnace nnderthe lower chamber, thence behind the end thereofithencebetween the two cham-- hers to the rear of the next one, and thusbetween, the several chambers oncompartments, and back of the rear endof each, up in the chimney on the top of the structure. In eachcompartment ventilators are placed near the top and bottom thereof,opening directly into the same from the outer air.

-The object of my invention is to obtain, with greater econ'omy of fuel,a more useful and eficient dry-house than those heretofore constructed.

Figure 1 is aview in isometrical perspective of my 4 improved dry-house.constructed with two compaltments.

Figure 2, a central longitudinal sectiouthercotl.

A A are. thewalls of the dry-house. The structure may be made of sheetmetal, so as to be portable, or of cast-ironin sections, or else solid,of masonry.

B Bare the the two compartments or drying-chambers, separated by anainspace, c, fig. 2, formed between the parallel inclined plates dd.This air-space c communicates freely at either end with similar spaces,6 c at the rear end of each compartment, which end spaces communicatewith the furnace-fluee. under the-lower chamberB, below and with aspace, 0'', over the upper chamber B, leading into the chimney D above,so as to form a continuous passage of a width equal to that of thecompartments from the furnace to the chimney, encompassing the-top,bottom,-

and rear end of each compartment.

E E are the doors of the two compartments or chambers B B. They areplaced, as illustrated, at opposite ends of the structure.

' F F are the furnace-doors.

G G are ventilating openings, closed by slides, so as to bethrown openat pleasure. These-ventilators are formed in the sides of the structureto open at the top and bottom of each compartment, and are arranged toform an upward current to carry off the steam or moisture extracted bythe heat from the substances in process of desiccation.

H H, fig. 2, are ways to receive the drying-frames m, upon which thearticles to be dried are placed.

My dry-house, thus constructed, is simple, yet singularly effective inoperation. The moisture expelled by the heat of the furnace-flue israpidly drawn poll and carried away by the cold-air currents through theside ventilators.

I claim as my invention.

The within-described drying-house, constructed of superimposedventilated drying-chambers, opening alternately at opposite ends of thestructure, each surrounded or inclosed at its top, bottom, and inner endby a flue or hot-air passage, extending continuously .from the furnaceto the chimney, substantially as and for the purpose herein set forth.

Witness my hand hereto this 2d day of April,-A.
